Temporal seizures due to hippocampal origins are very common among epileptic patients. Presented is a novel seizure prediction approach employing correlation and chaos theories. The early identification of seizure signature allows for various preventive measures to be undertaken. Electro-encephalography signals are spectrally broken down into the following sub-bands: delta; theta; alpha; beta; and...
Non-intrusive pressure measurement has the crucial role to the failure diagnosis and detection of hydraulic system where the conventional measurement instruments fail to make the necessary pressure readings within the sealed pipes. The measurement principle based on ultrasonic method was discussed in this paper. In order to make the processed method be suit for the hydraulic pipes which diameter of...
The real-time DSP-based cross-correlation speed measurement system is designed by using the digital signal processor TMS320F2812 as the core controller. the optoelectronic devices is used to detect the signal of cross correlation, which is processed by the wide-band amplifiers and the low-pass filters. Meanwhile the corresponding embedded multitasking software is developed. We evaluate the performance...
The method of detecting transmission is advanced based on cross-correlation theory, that utilizes modulated laser to produce modulated AC light and obtain double channels. The experiment shows detecting precision exceeds 0.5%.
In this paper we propose a new Handwritten Signature Recognition Algorithm. The Algorithm is based on pixel-to-pixel relationship between Images. The Algorithms are based on extensive statistical analysis, Standard Deviation, variance and Theory of Cross-Correlation. This is an extension work of Handwritten Signature Identification. This Algorithm supports the application environment and we strongly...
A time-difference ultrasonic wind speed and direction detection method is introduced. The two transducers are operated on unilateral V-mode. After the up-stream and down-stream echo signal being sampled, interpolated and cross-correlated, the time-difference of the echo signal is gained in accordance with the peak of the echo signals cross-correlated function. Through the time-difference, the wind...
